Lifetime Energy Tax Credit

[dyne]

For the year year 2010 the lifetime energy tax credit LIMIT is $1500. For the tax year 2011 the LIFETIME CREDIT LIMIT is $500. This is quite a reduction. Taxpayers will NOT be able to claim ANY lifetime credit for 2011 or future years IF they have already claimed an energy tax credit of $500 or more in previous years.
For the tax year 2010 WINDOWS must have a U factor <=0.30 SHGC <=.30.
For the tax year 2011 windows must have an ENERGY STAR rating to qualify for the credit.

NOW windows must have an ENERGY STAR rating to qualify for the credit.

They must have a manufacturer's certification (or else specific information to show they comply with the applicable standards). The Energy Star rating, by itself, is not sufficient.

And back to the individual maximums such as $200 max tax credit on windows.
